Spontaneous Magnetization of the O(3) Ferromagnet at Low Temperatures

We investigate the low-temperature behavior of ferromagnets with a spontaneously broken symmetry O(3) → O(2). The analysis is performed within the perspective of nonrelativistic effective Lagrangians, where the dynamics of the system is formulated in terms of Goldstone bosons. Unlike in a Lorentz-invariant framework (chiral perturbation theory), where loop graphs are suppressed by two powers of...

Sample environment at low temperatures

2014 A review of low temperature techniques as applied to neutron scattering studies is presented. Methods of temperature measurements especially carbon thermometry are discussed. Problems of heat transfer are treated in detail for different kind of samples and some solutions are proposed. Revue Phys. Appl. 19 (1984) 677-683 SEPTEMBRE 1984, The number of neutron scattering studies at temperatur...

Reset Noise at Low Temperatures

This paper presents results of the measurement and modelling of reset noise in charge-detection circuits of detector array multiplexers at low temperatures. To explain the temperature dependence of reset noise, it is proposed to take into account the source of noise associated with emission of electrons from interface states under the gate of reset transistor. It was found that at very low temp...

Microbial lipolysis at low temperatures.

It was found that lipase production during the growth of Pseudomonas fluorescens was not a function of the total number of bacteria. The optimal temperatures for bacterial growth and lipase production were determined as 20 and 8 degrees C, respectively. The lipolytic activity was studied in emulsions of olive oil at temperatures ranging from +8 to -30 degrees C. After an initially rapid lipolys...
